<p>The detection process is divided into three parts. <b>First</b>,
interest points are extracted from the search image (only inside the
domain of the search image).
This is done using the point detector and its parameters
selected once during the generation of the model. However,
<a href="#DetectorParamName"><i><code><span data-if="hdevelop" style="display:inline">DetectorParamName</span><span data-if="c" style="display:none">DetectorParamName</span><span data-if="cpp" style="display:none">DetectorParamName</span><span data-if="com" style="display:none">DetectorParamName</span><span data-if="dotnet" style="display:none">detectorParamName</span><span data-if="python" style="display:none">detector_param_name</span></code></i></a> and <a href="#DetectorParamValue"><i><code><span data-if="hdevelop" style="display:inline">DetectorParamValue</span><span data-if="c" style="display:none">DetectorParamValue</span><span data-if="cpp" style="display:none">DetectorParamValue</span><span data-if="com" style="display:none">DetectorParamValue</span><span data-if="dotnet" style="display:none">detectorParamValue</span><span data-if="python" style="display:none">detector_param_value</span></code></i></a> can be used
to specify different detector parameter values during the
<code><span data-if="hdevelop" style="display:inline">find_uncalib_descriptor_model</span><span data-if="c" style="display:none">find_uncalib_descriptor_model</span><span data-if="cpp" style="display:none">FindUncalibDescriptorModel</span><span data-if="com" style="display:none">FindUncalibDescriptorModel</span><span data-if="dotnet" style="display:none">FindUncalibDescriptorModel</span><span data-if="python" style="display:none">find_uncalib_descriptor_model</span></code> call. By changing these parameters,
it is possible to adjust to illumination changes between the model
generation and the online detection. However, it is recommended to use
the same values used to create the model (pass an empty tuple).
</p>
<p><b>The second step</b> of the detection process is to calculate
correspondences between the model points and the points that were
detected. The run time parameters of the descriptor can be adjusted
with <a href="#DescriptorParamName"><i><code><span data-if="hdevelop" style="display:inline">DescriptorParamName</span><span data-if="c" style="display:none">DescriptorParamName</span><span data-if="cpp" style="display:none">DescriptorParamName</span><span data-if="com" style="display:none">DescriptorParamName</span><span data-if="dotnet" style="display:none">descriptorParamName</span><span data-if="python" style="display:none">descriptor_param_name</span></code></i></a> and <a href="#DescriptorParamValue"><i><code><span data-if="hdevelop" style="display:inline">DescriptorParamValue</span><span data-if="c" style="display:none">DescriptorParamValue</span><span data-if="cpp" style="display:none">DescriptorParamValue</span><span data-if="com" style="display:none">DescriptorParamValue</span><span data-if="dotnet" style="display:none">descriptorParamValue</span><span data-if="python" style="display:none">descriptor_param_value</span></code></i></a>:

<p><b>The last step</b> is the estimation of a homography that describes

<p>Note that the domain of the search image should contain the whole

inside the domain of the search image. This means that if the domain
does not contain the full object to be searched for, the resulting

Note also that matches may be found even
if the reference point (origin) of the model lies outside of the
domain of the search image. Both is in contrast to shape-based
matching, where the domain of the search image defines the search
space for the reference point of the model.
